在数学的百花园里,有一类几何图形就像蝴蝶一样美丽娇艳,这就是“蝶形”.数学教学中,我们在欣赏“蝶形”之美的同时,也让我们产生了对“蝶形”的遐想.一、孕蝶——破茧而出例1如图1,已知直线m//n,A,B为直线n上的两点,C,P为直线m上的两点.(1)请写出图中面积相等的各对三角形.(2)如果A,B,C为三个定点,点P在直线m上移动,那么无论点P移动到任何位置,请指
In the mathematical garden, there is a kind of geometry that is beautiful and beautiful like a butterfly, which is “butterfly.” In mathematics teaching, while we enjoy the beauty of “butterfly”, we also give birth to First, the butterfly - broken cocoon out of a case 1 Figure 1, known lines m // n, A, B for the two points on the straight line n, C, P for the straight line m (2) If A, B and C are three fixed points and point P moves on a straight line m, no matter where point P moves to any position Please refer to
